抄録
We studied hormonal regulation of photomorphogenesis using cucumber seedlings with brassinosteroid-biosynthesis-specfic inhibitor, Brassinazole(Brz). When seedlings were germinated in the dark in half MS agar medium containing Brz, cotyledon opening was observed with inhibited hypocotylelongation. However, when they were germinated in distilled water, agar or soil containing Brz in the dark, neigher hook unfolding nor cotyledon opening was observed. In contrast, cytokinin treatment caused both of them in any of these growth conditions. We also analyzed endogenous BRs for light-and dark-grown seedlings by GC-MS. Light-grown plants accumulated more castasterone than dark-grown ones. Based upon these observations, we will discuss on the hormonal regulation of photomorphgenesis
